“…Corresponding to this, Tabur et al [9] showed that the boronized steels exhibit surface hardness over 2000 HV and provide improved abrasive and adhesive wear resistance. Comparison of other surface hardening treatments such as carburizing and nitriding with boronizing for steels used in the industry shows that the boronized steels have superior tribological characteristics [9,10]. In addition, although the wear resistance of the borocarburized layer has been determined to be higher in comparison with that for borided or carburized layers, the microhardness gradient in borocarburized layer has been found to be reduced in comparison with the only borided layer [11].…”

“…In Refs. [5,9], it has been shown that using surface treatments on engineering materials increases the wear resistance, decreases the friction coefficient, and improves corrosion resistance. Corresponding to this, Tabur et al [9] showed that the boronized steels exhibit surface hardness over 2000 HV and provide improved abrasive and adhesive wear resistance.…”

In this study, the hardness and wear behaviour of carburized and boronized AISI 8620 steels have been studied. The boronizing treatment increased the hardness of AISI 8620 steels from 395 HV0.1 to a maximal 1610 HV0.1 compared to the carburized steels and also significantly improved its wear behaviour. From obtained results, it can be concluded that boronizing is very effective surface hardening method for improving the wear properties of AISI 8620 steels.

“…This is in agreement with the reports of previous studies. [17][18][19][20][21][22] Comparing the wear rate of the borided steel with the unborided steel, the wear rate of the borided steels is approximately four times lower. The wear rate of the unborided sample was 81.2 × 10 -6 mm 3 /Nm; however, this value dropped to 1.28 × 10 -6 mm 3 /Nm (1323 K -8 h) as a result of the boriding process.…”

We have investigated the effect of the boriding process on the wear behavior of AISI D6 steel. The boride layer was characterized by light microscopy, X-ray diffraction and micro-Vickers hardness testing. The X-ray diffraction analysis of the boride layers on the surface of the steels revealed the existence of the FeB, Fe2B, CrB and Cr2B compounds. Depending on the chemical composition of the substrates, the boride-layer thickness on the surface of the AISI D6 steel was found to be 164.42 μm. The hardness of the boride compounds formed on the surface of the steels ranged from 1672 HV0.05 to 2118 HV0.05, whereas the Vickers hardness value of the untreated steels was 584 HV0.05. The wear tests were carried out using a ball-disc arrangement under dry-friction conditions at room temperature with an applied load of 10 N and a sliding speed of 0.3 m/s for a sliding distance of 1000 m. It was observed that the wear rate of the borided and unborided AISI D6 steel ranged from 1.28 × 10 -6 to 81.2 × 10 -6 mm 3 /Nm. Keywords: AISI D6, boriding, micro-hardness, friction coefficient, wear rate V {tudiji je bil preiskovan vpliv postopka boriranja na obrabo jekla AISI D6. Borirana plast je bila pregledana s svetlobno mikroskopijo, z rentgensko difrakcijo in izmerjena je bila mikrotrdota po Vickersu. Rentgenska difrakcijska analiza borirane plasti je pokazala prisotnost spojin FeB, Fe2B, CrB in Cr2B. Odvisno od kemijske sestave podlage je bila debelina borirane plasti na jeklu AISI D6 164,42 μm. Trdota boridov, nastalih na povr{ini jekla, je bila med 1672 HV0,05 do 2118 HV0,05, pri~emer je bila trdota neobdelanega jekla po Vickersu 584 HV0,05. Preizkusi obrabe so bili izvedeni na sestavu kroglica-plo{~a, pri pogojih suhega trenja pri sobni temperaturi, z uporabljeno obremenitvijo 10 N, s hitrostjo drsenja 0,3 m/s in potjo drsenja 1000 m. Ugotovljeno je, da je hitrost obrabe boriranega in neboriranega jekla AISI D6 v obmo~ju od 1,28 × 10 -6 do 81,2 × 10 -6 mm 3 /Nm.
